MSR Youth Assault Helmet 4 5 1 1
MSR Good price, good graphics, Hard to get on,...I almost sent the M back as it was initially really TIGHT to fit over the top of my head, but once on....(open the chin/mouth guard) it was a perfect fit. But as it is hard to get on....it is hard to get off. Just a very narrow opening.....so if you have a bigger head.....I do not, dont be surprised to find a tight fit... Im still glad I have this helmet though as competition helmets are very expensive. May 13, 2013
